Strategies for Meeting Our Reduction Target
Our ultimate goal is to be climate neutral. While our strategy for achieving that goal is evolving, our first priority is to reduce our total greenhouse gas emissions by reducing the energy intensity of our operations. To that end, we have cut our energy intensity 25% from 2002 to 2007 (energy consumption per million dollars in revenue). Xerox is finding success with these approaches:
Shifts toward More Energy-Efficient Technologies
One example is Xerox's commitment to emulsion aggregation (EA) technology, or chemical toner, which is estimated to require 25% less energy to manufacture than conventional toner.
Process Improvements That Reduce Energy Demand
Xerox has changed the way we make certain conventional toners, reducing energy demand by an estimated 15-25% per pound of toner. Xerox is its best case study for the efficiency of using digital multifunction systems in workplaces instead of standalone printers, copiers, fax machines and scanners. In Xerox locations worldwide, employees depend on networked Xerox systems for all document management needs. One multifunction system can cut energy consumption by half compared to several single function devices.
Increased Reliability of Xerox Equipment and Parts
Digital technology has improved the reliability of components inside our products. This reduces service calls, which results in fewer miles driven by Xerox technicians and less gasoline consumed. Longer-lasting parts also mean that less manufacturing energy is invested over the life of a Xerox product. One example is an office product print cartridge that needed replacement after 30,000 impressions in 1999 but in a newer product design lasts 500,000 impressions in 2007.
Equipment Upgrades and Energy Management Programs
Every year, Xerox facilities identify opportunities to reduce energy consumption through equipment upgrades and better energy management. Some Xerox facilities save energy through "free" cooling. In winter months, the facilities cool process water by running it through outdoor pipes instead of using chillers, which are the equivalent of industrial air conditioners.
Use of Renewable Energy Sources
By purchasing "green power", several Xerox sites, including those in the United Kingdom and the U.S., are taking advantage of opportunities to further reduce greenhouse gas emissions. An example is the purchase of renewable energy credits that largely offset electricity consumption at our Corporate Headquarters in Norwalk, Conn.
